0px;">光学传感器,就是将光线转换为鼠标核心芯片可以测量的电子信号的元件?/span></p><p style="box-sizing: border-box; margin: 20px 0px; padding: 0px; border: 0px; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB",

border: 0px;">光学传感器会以一定的众多性能参数(后面会提到),在你移动鼠标时不间断的工作,采集生成不同的可以量化的图像数据,作为芯片处理的图像依据,最终传递到电脑转化为屏幕上的显示信号?/span><span style="box-sizing: border-box; font-weight: 700; margin: 0px; padding: 0px; border: 0px;">而长期以来,鼠标传感器,还是以CMOS为主。所以,鼠标核心是一种“相机”设备,并无不妥?/span></p><p style="box-sizing: border-box; margin: 20px 0px; padding: 0px; border: 0px; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 18px; text-align: justify;">至于整个工作流程,大致是这样的:鼠标处理芯片(DSP电路、专用芯片、驱动芯片等),在单位时间内,收到传感器发来的图像信息,会将图像相互比较,以查看是否存在位移、位移了多少:这时处理芯片会使用控制方案的内部网格,将图像的所有像素都对齐并给出标识,当下一幅传感器发来的图像经过对比确认发生位移时,像素的位置在网格中就会变化,从而形成精确的位置信息变动?/p><p style="box-sizing: border-box; margin: 20px 0px; padding: 0px; border: 0px; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 18px; text-align: justify;">传感器和控制芯片知道两点之间的位移、所花时间,就可以知道鼠标移动速度以及加速度,控制芯片进行运算后,叠加其他操作(按键)数据,再向电脑传送,转化为操作显示效果。一切都非常快完成?/p><img

justify;">就目前来说,大部分的鼠标传感器,大家能从商品介绍页面中查到的核心指标,基本只有分辨率和回报率,少数游戏鼠标会有帧率和每秒英寸数。而从供应链文书方面,还能查到的有最大加速度等数据。简单来说,要了解全面的鼠标核心指标,建议首先找客服询问鼠标的传感器型号,然后可以到具体的厂商官网,查到该型号的PDF性能书,上面的性能就非常详尽了?/p><p style="box-sizing:
